FPV Workshop, also known as FPVBuilder Online, is a free online tool for planning and checking custom FPV drone builds. Designed for beginners and experienced pilots, it brings component selection, calculations and educational guidance into one workspace. Users can choose frames, motors, propellers, batteries, ESCs, flight controllers, receivers, FPV systems, radios and goggles, then review estimated weight, cost, current draw, thrust, hover time and flight time.

The builder supports a range of configurations, including 5-inch freestyle and racing quads, long-range builds, cinewhoops, and six- or eight-motor drones. It also flags basic compatibility risks involving components such as motors, batteries, ESCs, flight controllers and frames. Additional tools and guides cover FPV frequency planning, communication protocols, Betaflight and iNav diagnostics, MAVLink monitoring, soldering, repairs and first power-up checks.

FPV Workshop does not sell parts; it helps users compare options and prepare a parts list. Its estimates are approximate and should be checked against manufacturer specifications before purchasing or building
